使用paperclip在Rails 2.3.5中上传文件

Question

I have a Rails 2.3.5 application which has file upload functionality using paperclip. When I upload a file, the first time everything works fine. But the second time I try I get the following error message:

uninitialized constant ActiveSupport::MessageVerifier::Encoding

From the trace it looks like an issue with form_authenticity_token.

<% form_for @import, :html => {:multipart => true} do |f| -%>
    <ul>
        <li><%= f.label :source, "Select a file to import" %></li>
        <li><%= f.file_field :source %></li>

        <%= submit_tag 'Submit' -%>         
    </ul>
<% end -%>

If I clear the browser cache, I can get it working again. So I guess this is something related to session/tempfile etc. I just dont know what exactly :) Is there something I am missing here? Any help is appreciated

Thanks, Abhilash
